Hello there,

I'm trying to get OV3640 sensor working with mx53qsb based board.

I've got bsp from Adeneo and what I've done:

1. Setup iomux config in WINCE700\platform\iMX53_QSB\src\DRIVERS\IPUV3\CAMERA\bspcsi.cpp

2. Set env variable BSP_CAMERA1

I see that camera driver loaded and initialized, but next sample

DirectShow Sample Camera Application for WEC7 & WEC2013 - Download: DShowTest

doesn't work with message:

Builing the graph failed hr=0x1

RunCaptureGraph: Core components needed for RunCaptureGraph unavailable.

Later I found USB Camera in WEC7 can't show Video Render

After removing

[-HKEY_CLASSES_ROOT\Filter\{B87BEB7B-8D29-423f-AE4D-6582C10175AC}]

[-HKEY_CLASSES_ROOT\CLSID\{B87BEB7B-8D29-423f-AE4D-6582C10175AC}]

Sample starts to work, I see in debug that driver actually speak to camera over i2c and data starts to flow over CSI_D_ pads but all I see on screen is black rectange.

So why do I need to remove those keys to get basic samle working?

I've seen Camera Driver chapter in mx53smd windows embedded compact 7 reference manual, but mx53qsb bsp missing camera app test mentioned in mx53smd doc.

So where do I go next?

Hi alexeym,

There is an app in wince 6 bsp "CamApp" please see attached source, to port it to wince7 build it as a subproject and test it out.

Hope this helps
